In the series premiere of this drama, a hospital error that involved sending two newborns home with the wrong families is uncovered years later, when the girls are teenagers. The girls went on to lead very different lives: Artistic Bay Kennish (Vanessa Marano) grew up in a world of privilege, while athletic Daphne Vasquez (Katie Lecleric) was raised by a single mother and contracted an illness that left her deaf at a young age.

Kathryn questions why Regina isn't joining in the lawsuit against the hospital. Meanwhile, Daphne goes out with Liam and encounters new difficulties dating a hearing person; and Bay finds a kindred spirit in Ty, who hails from Daphne's old neighborhood.

Bay becomes curious about her birth father. Meanwhile, Kathryn deals with her nosy neighbors; and John takes an interest in Daphne's basketball games and meets Melody (Marlee Matlin), a friend of Regina's who works at Daphne's school.

Kathryn hosts a fund-raiser for Buckner Hall, and Toby's band provides the evening's entertainment. Meanwhile, Daphne is crushed to find out that she's been dating Bay's ex-boyfriend; and John and Melody's new friendship makes Kathryn uneasy.
